What are R Data Structures?
a) Ways to organize and store data in R
b) Functions for performing mathematical operations
c) Loops that handle iterations automatically
d) Methods for importing data into R
Answer:
a) Ways to organize and store data in R
Explanation:
R data structures are different ways of organizing and storing data in R. They allow you to manage, manipulate, and analyze data efficiently. R provides several built-in data structures, each suited to different types of tasks and data.
The primary data structures in R include:
- Vectors: A basic data structure that stores elements of the same type.
- Lists: A versatile data structure that can store elements of different types.
- Matrices: A two-dimensional data structure that stores elements of the same type.
- Arrays: A multi-dimensional generalization of matrices.
- Data Frames: A two-dimensional data structure that can store elements of different types, similar to a table in a database.
- Factors: A data structure for handling categorical data.
Understanding and using these data structures effectively is key to performing data analysis and statistical computations in R.
